Sodium chloride is one of the most basic raw materials in the chemical industry, mainly composed of sodium chloride, sodium nitrite, etc. It is used to produce hydrochloric acid, caustic soda, soda ash, hydrogen, chlorine and other chemical products. Industrial salt can be divided into industrial granular salt and industrial refined salt according to processing or not. Industrial refined salt has higher sodium chloride content and less impurity content
As a common name of sodium thiosulfate, DASUDA is also called Haibo and hyposulfite,with five crystal waters (na2s2o3.5h2o), so it is also called sodium thiosulfate pentahydrate,which is tasteless and colorless transparent crystal,deliquescent in humid air,soluble in water,and weak alkaline aqueous solution
Sodium metabisulfite is a white or yellow crystalline powder or small crystal,with strong SO2 smell and specific gravity of 1.4. It is soluble in water and the aqueous solution is acidic.When contacting with strong acid,SO2 will be released to generate corresponding salts. If it is kept in the air for a long time,it will be oxidized to na2s2o6,so the product cannot be kept for a long time.Above 150 ℃,SO2 will be decomposed
Sodium carbonate(Na2CO3),molecular weight 105.99.The purity of chemicals is more than99.5%(mass fraction),also known as soda ash, but it is classified as salt,not alkali.Also known as soda or soda ash in international trade.It is an important organic chemical raw material, mainly used in the production of flat glass,glass products and ceramic glaze.It is also widely used in domestic washing,acid neutralization and food processing
A new kind of water purification material, inorganic polymer coagulant, has a high degree of electro neutralization and bridging effect on colloid and particles in water, and can remove slightly toxic and heavy metal ions strongly, with stable properties. The test method can be tested according to the international standard GB 15892-2003. The polyaluminium chloride is a kind of inorganic high polymer water treatment agent with high molecular weight and high charge, because of the bridging effect of hydroxyl ion and the polymerization effect of multivalent anion
Sodium sulfate,inorganic compound,also known as mirabilite,white,odorless,bitter crystal or powder,hygroscopic.The shape is colorless, transparent,large crystal or granular small crystal.Mainly used in detergent,desiccant,dye diluent,water glass,glass,enamels,paper pulp,refrigeration mixture,analytical chemical reagent,pharmaceutical products,etc
Citric acid(CA for short)is an important organic acid,also known as citric acid.The molecular formula C6H8O7,Is colorless crystal,which often contains one molecule of crystal water,odorless,has strong acid taste and is easy to dissolve in water.It has many uses in industry,food industry,cosmetic industry and so on
